Using the Battery Pack
Accurately Displaying Battery Capacity
The battery pack has a function for measuring, storing, and learning about battery capac­
ity. Using this function properly to accurately display remaining battery capacity requires
that the battery pack be fully charged (charged to 100%), then fully discharged, and then
fully charged again.
Use the procedure presented below to fully charge the battery pack, then discharge it, then
charge it again. This procedure should be performed once after you purchase the com­
puter. As you use the battery pack over a long period of time, the remaining capacity
display may become inaccurate due to aging of the battery pack and other factors. The
procedure described below should be repeated.
1
Attach the battery pack, then connect the AC adapter
In some cases, the remaining capacity display (shown through key actions)
may give a reading of 100% capacity even though the battery indicator remains
onmge. Simply continue charging the battery pack until the indicator turns green.
2
Once the battery indicator turns green, remove the AC
adapter
